JAMES ONEIL, OF GORGONA, CANAL ZONE.

EMERGENCY-COUPLING.

Application led November 3, 1909.

Specification of Letters Patent.

Patented Aug. 8, 1911.

Serial No. 526,024.

To all whom it may concern:

Be it known that I, JAMES ONEIL, a citizen of the United States, residing at Gorgona, Canal Zone, have invented certain new and useful Improvements in Emergency-Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention consists of a device to be used as an emergency coupler in case of a train breaking in two as a result of a broken or worn lock; a broken knuckle tongue; or on account of the knuckle and jaw having become worn so as to pass each other.

It is the intention that this device shall be marde part of the equipment of the engine and that same shall be removed from its emergency use at the end of the trip and returned to the engine, whereupon drawhead defects can be marked and reported,

In the drawings forming part of this specification, like numbers of reference denote like parts wherever they occur, and Figure l is a. top plan view; Fig. 2 is a side elevation; F ig. 3 is a detailed view, on an enlarged scale, of the bridle; and Fig. 4 is a detailed view, on an enlarged scale, of the bridle coupling-pin.

The bridle 1 is provided at its ends with arms 2, which contain perforations 3. Said perforations are designed to aline with a perforation found in the end of knuckle 4L. By slipping the bridle over the jaw and opposite said hole in the knuckle, the two perforations 3 are brought into alinement with the perforation through the knuckle 4, and pin 5 can then be slipped through one of the perforations 3, after which it can be passed through the perforation in the knuckle 4, and then through the other perforation 3. A linchpin or Cotter 6 can then be passed through hole 7 in pin 5 to keep the pin 5 from movement, and thus the bridle is held securely in place, while the knuckle 4 is thereby bound to the opposite drawhead.

The use of two such bridles makes a good emergency coupling, since a knuckle of each draw-head is thereby attached to the opposite draw-head. Furthermore, when the draw-bar carrier is down, two such bridles can be used to support the draw-head.

Many minor changes in the form, arrangement, and the location of the several parte may be made without departing from the nature and spirit of this invention.

I claim:

The combination, with a pair of drawheads provided with pivoted knuckles, eachv knuckle having a perforation formed through its end, of a U-shaped bridle pivoted to each knuckle and arranged to engage the other draw-head, each bridle including a pair of lateral terminal arms formed at their ends with perforations registering with the perforation in the knuckle to which said bridle is pivoted, and a pin projecting through said registering openings, the arms of each bridle extending one above and the other beneath the draw-head with which it is engaged.

In testimony whereof I have aiXed my signature in presence of two witnesses.

JAMES ONEIL.
